In Virtual Machine Manager admin console, I used the 'New virtual machine' wizard and created a machine from an existing template.
When I got to the Configure Hardware step, I selected the primary hard disk (which is a dynamic) disk and tried to increase it's maximum size, but this control is disabled so I can't increase it.
It's not big enough for my purposes. how do I increase the maximum size of the hard-disk?
Edit: I am able to add a second hard disk of a size I specify. That's not useful though as I'm trying to install some software, some of which insists on being on drive C.
